To carry out a radial forearm flap, the radial artery is usually harvested, incurring severe donor site morbidity. Advances in anatomical knowledge discovered constant radial artery perforating vessels, enabling the subdivision of the flap into smaller components suitable for a wide range of differently shaped recipient sites, with marked reduction of downsides.
Eight pedicled or free shape-modified radial forearm flaps were used to reconstruct upper extremity defects between 2014 and 2018. Surgical technique and prognosis were examined. Skin texture and scar quality were assessed on the Vancouver Scar Scale while function and symptoms on the Disabilities of the Arm, Shoulder and Hand score.
At a mean follow-up of 39 months, no cases of flap necrosis, impaired hand circulation or cold intolerance were found.
The shape-modified radial forearm flap is not a new technique, but is poorly known by hand surgeons; in contrast, our experience showed it to be reliable, with acceptable functional and esthetic outcomes in selected cases.
为了进行游离前臂皮瓣移植，通常需要采集桡动脉，这会导致严重的供区并发症。解剖学知识的进步发现了恒定的桡动脉穿支血管，这使得皮瓣可以分为更小的成分，适用于广泛的不同形状的受区，显著降低了缺点。
2014 年至 2018 年间，我们使用 8 个带蒂或游离的形状改良的游离前臂皮瓣来重建上肢缺陷。检查了手术技术和预后。温哥华瘢痕量表评估皮肤质地和瘢痕质量，而手臂、肩部和手功能障碍评分则评估功能和症状。
平均随访 39 个月，未发现皮瓣坏死、手部循环受损或不耐寒的情况。
形状改良的游离前臂皮瓣并不是一种新技术，但手部外科医生对此知之甚少；相比之下，我们的经验表明，在选择的病例中，它是可靠的，具有可接受的功能和美观效果。
